PC Kate Rainscourt said: "This is a high value theft and we are sure this isn't the first time that these men have committed this kind of offence, therefore we would like to be able to identify them. We would ask that the public take a look at the CCTV picture provided and if they recognise the men, they should get in touch as soon as possible."

Anyone with information should contact Gosport police station on 101 or Crimestoppers anonymously on 0800 555 111.
